On our last day in Venice, the heavens opened, there was also an exceptional high tide, so there was some flooding. It was quite interesting, as it was something I had only seen on the media and I did wonder about the boards that were put out for walking on. We did have go, but it was a little scary as they are quite high and people did push past you, I should think if you fell off it could hurt a bit. Once we left the square the flooding subsided and we just had to deal with large puddles. The flooding gets a lot worse than we experienced and until they work how to stop it, the city will continue to flood causing untold damage to the buildings.
